To all whom 'it may concern:

. Be it known that I, IEssE ALEXANDER, a citizen of the United States, residing at borough of Brooklyn,

Kings county, New York, have invented certain new and useful Improvements in Mile-Registers, of which the following is a full, clear, and exact description.

My invention relates to improvements in registering mechanism, and particularly a mile register for vehicles.

a The object of the invention is to provide asimple and accurate construction for registering the movement of a vehicle, and indicating the same in a convenient manner. I

' The invention consists in improvements, the details of which are illustrated in the accompanying two sheets of drawings.

The .construction comprises a casing containing the movable parts of the indicating apparatus. Two series of drums are provided for indicating the total distance traveled by the vehicle. These drums are operated by a train of gears, which train is operated by an electro magnet. The circuit from the magnet includes a'suitable make and break device controlled by the running gear of the vehicle. The distance traveled is therefore indicated whether the vehicle moves in a forward or backward. direction. One of the sets of drums may be'disconne'cted from the train and reset by simple accessible mechanism.

My invention also comprises improvements in the details of the mechanism whereby the resetting may be accomplished expeditiously.

' 1 is a front view of a mechanism embodying the improvements of my invention. Fig. 2 is a rear 1 view'of the same, the back of the case being removed; Fig. 3 is a view of the right hand side of the mechanism frame and gears. Fig. 4 is a'viewof the left hand side. Fig. 5 is a sectional view. of the right hand side of the mechanisr'nof Fig. 2, (a view from the left as seen in figure.) Fig. 6 is a sectional view of the upper I series of drums. Fig. 7 is an enlarged detail 5: the releasing gear. Fig. 8 is an end view of one of the indi- 1 is the for the mechanism. 10isthe back.

1111 11 11 arefllugs for the attachment of the back. 12 and13 are openings-or windows in the front ofthe'casing.

2 and 20 are the side plates of the frame for carrying the mechanism. I I

21-2223 are bars for connecting the frame plates. The frame is guided in the casing by the lugs 11, but may be removed, together with alltlie operating parts.

3 and 30 are magnet coils.

33 is an armature member. i

34 is a spring normally holding the armature in its raised position. v p

3536 are pins projecting from the pole pieces 31-32 and serve as guides for the armature member 33.

37 is a rod carried by the armature member 33 and pivotally connected in a slot in the pawl 38.

39 is a shaft pivoted in the frame plates 220, and carrying eccentrically of its axis the pawl 38. The shaft 39 is formed with a bond, as shown in Figs. 2 and 5, near the center, and the pawl 38 is mounted rigidly or fixed on the shaft at this point eccontrically of the pivotal axis'of the shaft, so that when the armature 1ncmbcr33 is drawn downward by the magnet, the rod 37 rocks the pawl 38 downwardas well as forward and the spring 34 causes a reverse movement when the magnet is deenergized. g v

4 is a ratchet wheel mounted on the shaft 40 directly beneath the pawl 38, which is rotated stop by step as the pawl is operated, the pawl normally holding the ratchet stationary, as shown in Fig. 5. 7 5

41 is a pinion on. the end of the shaft 40 meshing with the gear 42.

43 is a pinion rotating with the gear 42 in mesh with the wheel 44. v

45 is the shaft of the gear wheel 44. 30

46 is a pinion carried by the opposite end of the shaft and in mesh with the two gears 4748.

5 is the main drumshaft carrying a series of drums 51 &c., for indicatingtenths, units, tens, &c., of miles.

52 is a gear on the shaft 5 in mesh with the gear i7 and driven thereby. Movement is transmitted from one drum to the other in this series of main indicating drums through gears 53 in the same manner as hereinafter described in regard to the upper series of drums.

6 is the shaft of thc secondary series of drums (il-62- 6364' for indicating miles traveled during a trip. I This shaft 6 is driven through gear 60 which is normally in mesh with gear 48; The (lllllll 61 is fast on the shaft 6 and the other drums are loosely mounted but properly held from relative longitudinal movement. 3

65 is a headed pin projecting through the drum 61 and held in its normal position by a spring 66.

67 is a beveled stud projecting from drum 62 over which the pin 65 may slide when the drum is rotated clockwise, as viewed in Fig. 3, but which intercepts the pin 65 when the drum 61 is rotated in a reverse rotation, thus causing the drums to rotate together when the pin contacts with-the back of the stud. Similar pins and studs are provided between the other drums of the series.

68 is a stud projectingfrom the frame plate 20 for on.- actionwith the pin carried by the loose drum to bring it 31 and 32m the poles of the two magnets to rest at the zdo position when re-sct.

69 is a handle for turning the shaft 6, which handle is preferably screw-threaded onto the shaft 6 and projects through the case 1. i I I I 7 is a countershait carrying a series of starwheels 7172- 7 3 for transmitting movement between the drums when in engagement therewith.

74 is a stationary rod which engages between the teeth of the star wheels when they are retracted from the drums, for the purpose of holding them from rotary displacement.

8 is a handle projecting outside the casingscrewthreaded onto a stud 80 of a release mechanism pivoted in the frame, and consisting of the plates 81 and 82 and a connecting bar 83. The shaft 7 projects through curved cam-like openings in the plates 81 and 82, so that when the handle 8 is partially rotated, the shaft 7 and star wheels 7l-7273 are disengaged from the drums 6i62ii3-64. I

9 is a screw-threaded post seated in the frame plate 2 and affording abearing for the gear 48.

91 is a spring normally holding the gear 48 in'mesh with the gear (50. r

'92 is a pin longitudinally slidable within the hollow post 9 and-carrying a cross-piece 93, which engages beneath the gear 48. The end of the plate 82 is formed with a bevel or cam surface 84 against which the end oi the pin 92 rests. When the handle 8 is partially rotated it tilts the plates .81 and 82 and thus forces the pin 92 outward and disengages the gear 48 from the gear 60. The drums may then be returned to a zero position by rotating the handle 69. This provides a quick and handy means for re-setting the drums after a trip. The lower main series of drums would seldom require resetting since those herein shown are intended to register up to 99,9999 miles. i i

Any suitable form of mechanism may be employed to make and break the electric circuits through the magnets 3 and 30. Each make and break draws down the armature 33 and advances the ratchet 40 through the space of one tooth whether the vehicle is going forward or backward.
